Fair point, I'm sure it was kawi that made a radiator unit with a separate oil cooler section built onto the bottom at some time.
I want to say Honda had them as well. Very trick.

It's a power band container.

I agree with the restricted air flow part. Ive questioned them being behind the radiators. But still gets more surface area cooled. In contrast to the side mount, with 50% of it almost directly on the head. Who knows? Everbody thought putting a powerband in bikes years ago was crazy!

FIREfish148, I didnt even see your post when I put that in. Coincidence.

I would think they'd benefit more from a fuel cooler in Colorado. A small box with coiled tubing, packed with dry ice. Same principle as an ice chest with many tubing coils, packed with ice, and a hose/nozzle on the out side. Eliminates the need to constantly add ice to the keg barrel. Just thinking back to the fuel boiling issues in the earlier days of Thunder Valley.
We built "cool cans"way back in the 80's out of a water bottle and copper tubing for our road race bikes. Boiling temp drops as you go up in altitude.

That is a full factory engine that is rebuilt every race. They have to run a oil cooler to make it through a single race? Must be some reliability issues with those engines at that level.

I cant imagine the 450 motors tweaked to such a level like the 250s are.

KTM had to run a fan on their bikes outdoors due to cooling issues after Dungey signed with them and they came out with the first Factory Edition. Nothing new.

Because if it is punctured and all the oil sprays out, there won't be any left in the engine. That would be not good for finishing the race.

I wonder how much of a difference it's making with it than when they weren't running it

That was Honda (Gieco as well, I believe).

Remeber it adds extra oil to the system also. More oil will always help with keeping vital engine parts cooler.
